15:56
Fix a possible heap-buffer-overflow in parse_htmlblock() introduced by [1e919d601f774fdb]. This is not related to footnotes but was revealed by fuzzing (case 80cbb6b185807e98a953426af7b1f802c9d13957). ... (check-in: bc4c5b63 user: george tags: markdown-footnotes)

Revert Makefile.in to normal builds (leave a few comments about fuzzing). ... (check-in: 94077966 user: george tags: markdown-footnotes)
13:16
Fix a use-after-free bug in handling of nested inline footnotes. The bug was discovered by fuzzing with '-fsanitize=fuzzer,undefined,address -DFOSSIL_FUZZ' appended to TCCFLAGS in Makefile.in. It's noteworthy that the ',undefined,address' part was essential to find the bug (otherwise just 'double-free' was reported). Many thanks to Stephan for documenting the fuzzing procedures and support. ... (check-in: 31e5df5f user: george tags: markdown-footnotes)
